Message from the President<\/span>\r\n<\/span><\/div>\r\n
\r\n\r\n2018.03.20<\/span><\/span>\r\n

In 2018, we celebrated the 150th anniversary. We would like to express our sincere gratitude for your continued support and patronage.\r\nWe offer great value through our “integrated in-house production system from glass molding processing to assembly”. We have processing equipment to make molded glass lenses with \u03c61.6\u339c-\u03c6300\u339c. Our product line is mainly for medical devices, factory automation equipment, and semiconductor related products. We manufacture various shapes of glass molded products for a wide range of applications such as prisms and lenses. To meet the current market demands for high quality lenses with a shorter delivery time and lower cost, we are striving to strengthen corporate capabilities and productivity.<\/p>\r\n

IoT, AI and industrial robots have been recently advocated as essential to every field. We have been researching how we can utilize the cutting-edge technologies to our high-mix low\r\nvolume production, and we continuously endeavor to improve our processing technologies and equipment, etc.<\/p>\r\n

We will continue to further enhance our “MONOZUKURI”, manufacturing to meet customer requirements more than ever. We look forward to your continued support and encouragement.<\/p>\r\n\r\n
